PHP Arrays and Control Structures

Replace the hard coded values in the output with the name and email values from the contacts array. Kindly help!

//edit this array
$contacts[] = array(
  'name' => 'Alena Holligan',
  'email' => 'alena.holligan@teamtreehouse.com',
$contacts[] = array(
  'name' => 'Dave McFarland',
  'email' => 'dave.mcfarland@teamtreehouse.com',
$contacts[] = array(  
  'name' => 'Treasure Porth',
  'email' => 'treasure.porth@teamtreehouse.com',
$contacts[] = array(
  'name' => 'Andrew Chalkley',
  'email' => 'andrew.chalkley@teamtreehouse.com',

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n";
echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n";
echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n";
echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n";
echo "</ul>\n";

you'll need to add the following to output each array into the echo:

each contacts array is an index array and then each array inside the contacts array is an associative array, hence why I'm calling the index number then the associative array key by it's name. Hope this helps :)

echo '<li>' . $contacts[0]['name'] . ' : ' . $contacts[0]['email'] . '</li>';
echo '<li>' . $contacts[1]['name'] . ' : ' . $contacts[1]['email'] . '</li>';
echo '<li>' . $contacts[2]['name'] . ' : ' . $contacts[2]['email'] . '</li>';
echo '<li>' . $contacts[3]['name'] . ' : ' . $contacts[3]['email'] . '</li>';

I also figured out a solution. I realized that you can not output an array directly in a string and hence the need to use curly braces.

echo "<ul>\n";

//$contacts[0] will return 'Alena Holligan' in our simple array of names. echo "<li> {$contacts[0]['name'] : $contacts[0]['email']}</li>\n"; echo "<li> {$contacts[1]['name'] : $contacts[1]['email']}</li>\n"; echo "<li>{$contacts[2]['name'] : $contacts[2]['email']}</li>\n"; echo "<li>{$contacts[3]['name'] : $contacts[3]['email']}</li>\n";

echo "</ul>\n";
